Assessment on Ecological Risks of Land Consolidation
(0) With the project planning and design of land consolidation, an index system for the ecological risks assessment is set up based on the identification of the ecological risks with 14 indexes and three factors as water, soil and biology. The index standard is studied out, and the weighting allocation of the index system is workout by AHP. The integrated index of ecological evaluation (ER) is established. The results of the trial use of the suggested index system indicate that, (1) The ER is reduced 28.94 after land consolidation, and the ecological risk is down from level Ⅲ to level Ⅳ; (2) By the element analysis, the water ER is reduced from 21.53 to 6.16, its contribution to the ecological risk is 53％; The ERs of soil and biology are respectively 12.97 and 0.79, their contribution of ecological risk are lower than water.
